Report
Summary
The City is designing and constructing four production wells and six ASR wells by 2021. Water pumped from the wells will be used to supplement water resources during times of long-term water shortages, emergency outages, and to meet water system demand balancing.
Carollo Engineers, Inc.'s services include: organizing, coordinating, and providing technical advice; and overseeing the necessary resources required to conduct the design, construction, permitting, public communications, and initial operations of production and ASR wells. Carollo Engineers, Inc. will ultimately be responsible for assisting the Water Services Department with planning and implementation of the well program.
This increase in contract value is necessary to expand the capacity of the Program Management Services contract to include scope of work for construction-related services as well as design services that were approved by Council on June 28, 2017.
Procurement Information
Carollo Engineers, Inc. was chosen for this project using a qualifications-based selection process according to section 34-603 of the Arizona Revised Statutes.
Contract Term
The term of this contract is expected to coincide with the duration of Phase I of design and construction, which is expected to be completed by 2021. Contract work scope identified and incorporated into the contract prior to the end of the contract may be agreed to by the parties, and work may extend past the termination of the contract. No additional contract work scope changes may be executed after the end of the contract term.
Financial Impact
The initial contract value was established at a not-to-exceed amount of $2,000,000. If approved, this amendment would increase the contract amount by $820,000, including all subconsultant and reimbursable costs, for a new total contract value of $2,820,000. Funding is available in the Water Services Department's Capital Improvement Program budget. Contract payments may be made up to contract limits for all rendered contract services, which may extend past the contract termination.
